The invention discloses a hydrogen fuel commercial vehicle power output prediction method, system and device and a medium, and belongs to the technical field of intelligent vehicles. Whether a vehicle enters a climbing or downhill section or not is judged by measuring the driving inclination angle of the vehicle in the driving process in real time and according to the inclination angle change; the running acceleration and deceleration state of the vehicle is judged by measuring the running acceleration of the vehicle, so that the power demand of the hydrogen fuel pile in the climbing or downhill stage of the vehicle is predicted, and the power demand is proposed for the pile in advance before rear wheels of the hydrogen fuel commercial vehicle enter the climbing stage; therefore, the hydrogen fuel commercial vehicle obtains enough power support before rear wheels enter a slope, and the influence of insufficient stack power output caused by system delay is reduced.
本发明公开了一种氢燃料商用车功率输出预测方法、系统、装置以及介质,属于智能汽车技术领域。通过实时测量车辆在行驶过程中的行驶倾角并根据倾角变化判断车辆是否进入爬坡或者下坡路段;通过实施测量车辆的行驶加速度判断车辆的行驶加减速状态,从而实现对车辆的爬坡或下坡阶段时氢燃料电堆的功率需求的预测,以在氢燃料商用车的后轮在进入爬坡前提前对电堆提出功率需求,使氢燃料商用车在后轮进入爬坡前获得足够的动力支持,减小因系统延迟导致电堆功率输出不足的影响。
